The Sitara, particularly when it is operating with a Linux OS, is much more sophisticated than any of the PIC's.
I suggest you carefully read the BeagleBone Black Systems Reference Manual (SRM). http://elinux.org/Beagleboard:BeagleBoneBlack#LATEST_PRODUCTION_FILES_.28C.29 I suggest you purchase a copy of Derek Molloy's "Exploring BeagleBone: Tools and Techniques for Building with Embedded Linux" http://www.amazon.com/Exploring-BeagleBone-Techniques-Building-Embedded/dp/1118935128/ref=sr_1_1 I suggest you download Derek Molloy's Header Charts, which summarizes all the I/O pins for the capes, and how they can be assigned through the pin-mux (Device Tree). http://exploringbeaglebone.com/chapter6/#BeagleBone_BlackHeaderCharts The combination of the SRM and Molloy's Header Charts have all the information you need to assign and use the BBB pins, but there is a lot of background and application information that will keep you from making mistakes. --- Graham == On Monday, September 7, 2015 at 12:19:32 PM UTC-5, StefDrums wrote: > > Hello to all, > I'm prototyping a new cape board for BeagleBone Black. > I have designed most of the circuit and now it's time to connect all the > thing to the beaglebone. > I have a problem: I can not figure out whitch PINs can I use. > I read the BeagleBone Black System Reference Manual and the AM335x Sitara > Processors datasheet, but I can't find where all the pin' s feature are > explained. > I some different kind of connection: > - 1 I2C bus (it's OK, ill use P9 17 and 18 PINs) > - 1 UART with CTS and RTS > - 2 IRQ from push buttons > - 4 analog channel (it's OK, ill use AINs PIN on P9)- 2 SPI bus > - 3 PWM channel (standard PWM modulation, fixed frequency, variable duty > cicle) > - various I/O (no problem for this) > > Until now I have always designed on less complex systems, like PIC24 and > PIC18 based board.
